I don't mind waiting some, as long as it's within reason.
When things get really backed up or there is just a super slow group ahead, then it's irritating. By and large, most of the time the slower groups let my friends and I play through if there is an open hole ahead.
What really bothers me the most about slow play is when the people behind me are breathing down my neck and hitting into me even though things are backed up and I'm waiting on the group ahead of me with nowhere to go.
